At its inception, solar power technology was dubbed a "rich man's toy" due to its high price tag, a situation that lasted until the 1970s when, with funding from the Exxon Corporation, lower-cost solar cells were introduced, plummeting from $100 per watt to $20 per watt.
This situation continued until the 1970s when, with funding from Exxon Oil, lower-cost solar cells were introduced and their price plummeted from $100 per watt to $20 per watt. By the 21st century.
At the beginning of the 21st century, the iteration of solar technology became more and more amazing, and now in Germany and other developed countries, solar power is already cheaper than thermal power, while in China, Hanergy.
In China, "rooftop solar" systems produced by companies such as Hanergy and Yingli have also made their way into ordinary homes. Today, the use of solar power has long been not the patent of the rich, even.
Even residents living in remote and poor areas have the opportunity to enjoy the convenience of solar power.
Why has solar power been so successful in remote areas?
According to media reports, in recent years, small solar power plants have become a new favorite in the Indian electricity market. Prior to this, the lack of electricity was a long-standing problem that plagued Indian society.
And now, countless small solar power stations shoulders the responsibility of supplying electricity to local residents. A local grocery store owner said in an interview, "In the past, because of the lack of
In the past, because of the lack of electricity, my store had to close very early, because at night it was dark. Now that we have electricity, we can stay open late." Not only in India, but in vast areas of Asia, Africa and Latin America, stand-alone solar systems have grown considerably over the past few decades.
Why has solar power been so successful in remote and underdeveloped areas? This is where we come to the "on-grid" and "off-grid" aspects of electricity. Generally speaking, electricity
feed-in" means that the electricity produced by a thermal or hydroelectric power plant is uploaded directly into the grid and becomes part of the power system of a region, or even a country.
The term "off-grid" means that the electricity produced through thermal or hydroelectric power plants will be directly uploaded into the grid and become part of a regional or even national power system. Off-grid, on the other hand, means that the application of electricity is localized, with electricity produced locally for the sole use of a village, a factory, a small residential area, or even a single house.
It is also referred to as a stand-alone power system because it is used only by a village, a factory, a residential area, or even a single house.
Stand-alone solar systems are useful in areas where traditional energy sources are in short supply or too remote for grid construction to reach. In China, in remote mountainous areas such as Yunnan
In China, remote mountainous areas such as Yunnan, Guizhou and Sichuan, as well as in Xinjiang and Tibet, there are varying degrees of power shortages and inadequate power grid support. And solar off-grid power generation, because it is self-generated electricity, does not need to go through long-distance power transportation, and does not require infrastructure construction such as power transmission towers and hundreds of kilometers of power lines.
Therefore, it has become an important source of electricity for local people.
In China's Tibetan Ali region, for example, Ali is known as the "roof of the roof of the world", because of the harsh natural environment, weak power infrastructure and other reasons, power supply.
In Ali's Gangdis Tibetan Medical College, local students only at 21:00 to 24:00 every day the three hours of electricity available, morning and evening reading only
Can rely on flashlights. But Ali as the world's most abundant solar energy resources in the region, the use of solar power has become an excellent choice. In June of this year, the country's largest
Hanergy, the largest thin-film solar energy company in China, sent an engineering team to Ali to build a solar power plant for the Gandhian Tibetan Medical College, the project took 21 days.
At 7:00 pm on July 5, the light bulbs in the house were lit up and the whole medical school was brightly lit. With the formal completion of the thin film solar power plant, the local teachers and students finally ended the history of only 3 hours of electricity available every day.
With the completion of the thin-film solar power plant, local students and faculty finally ended the history of having only 3 hours of electricity available every day.
